Germany's Ralf Schumacher won a hard-fought battle of the brothers in Canada today to give Williams theirsecond victory of the Formula One season.
World champion Michael Schumacher, who had started on pole position and was chasing his fifth win in Montreal, was second to extend his lead inthe championship to 18 points after a nightmare afternoon for title rival David Coulthard.
McLaren's Coulthard retired 13 laps from the end with a blown engine and has 40 points compared to Schumacher's 58. The Briton had scoredpoints in each of the previous seven races.
Finland's Mika Hakkinen, two times world champion, was third in a McLaren. Finland's Kimi Raikkonen in a Sauber was fourth.
It was Ralf's second career win, his first being at the San Marino Grand Prix at Imola in Italy in April. That was Williams' first success since 1997.
Ralf and older brother Michael had scrapped wheel to wheel for much of the race run in bright sunshine before Ralf decisively took the lead on lap46 as Michael had his pit stop.
The Williams driver, who started alongside Michael on the front row, broke the lap record before pitting himself and coming out clearly in the lead.
But Colombian Juan Pablo Montoya, who had been involved in a scuffle and acrimonious exchange with local favourite Jacques Villeneuve on Fridaynight, crashed out.
The Formula One rookie lost control coming out of L'Epingle corner on the approach to the Casino straight, ploughing into the barriers. "I don'treally know what happened," said Montoya.
The incident also ended the race of Ferrari's Brazilian Rubens Barrichello, who had spun early in the race and dropped from third to 14th placebefore climbing back through the field.
He had been challenging Montoya for 10th place and swerved across the track to avoid the Colombian, smashing into the barrier on the otherside.
Villeneuve fared no better, pulling over on lap 35 while 10th. He got out of his BAR and walked back to the pits.
"Something happened and the car wasn't driving any more," said the Canadian former world champion, who described the weekend as the worst ofhis racing career.
Jaguar's Eddie Irvine and German Nick Heidfeld in the Sauber were early casualties, going out on the second lap in a collision that Heidfeld blamedon the Irishman.
"He tried to overtake me but went into my back," said the German, who has been shunted out early in the last two races.
Benetton team mates Giancarlo Fisichella and Jenson Button endured another nightmare afternoon, with the Italian going into the back of hisyoung team mate on lap one.
That ended Fisichella's race while Button had to suffer a 10 second stop/go penalty for jumping the start.
Jordan were looking good for most of the race but Trulli - running in fourth place -lost his brakes with just six laps to go.Ricardo Zonta, who was standing in for Frentzen finished the race just outside the points.
